I have some Philips Hue bulbs. When I first setup HA, I added the discovered SLZB-06, not realizing that was actually ZHA. I want to use Z2M. I had paired the bulbs with it. I later removed the bulbs from ZHA, and tried to get them to pair with Z2M. No luck.
I can reset the bulbs both by touchlink and the Philips/HUE builb code. In both cases the bulb blinks a couple times. I know that the SLZB-06 can talk to it. However it never discovers the light. I’ve got set to “allow all”.
I tried removing zigbee2mqtt reinstalling it. No change. I removed it again, this time removing the zigbee2mqtt directory under /config.
The SLZB-06 is running the latest firmware. I’ve read countless web pages on resolving problems with Z2M, but nothing has helped.
I would start by pairing a non Hue device just to make sure your Z2M is working correctly.
Once you are sure Z2M is good I would suggest doing the same thing I did:
Ensure both Zigbee networks (ZHA + Z2M) are functioning correctly.
Put Z2M into “Permit join” mode.
Disconnect the Hue Bulb from the ZHA network.
The light does its RGB color cycle to show its disconnecting from ZHA then does its (white) flash cycle as it joins Z2M.
Unless I have both networks available I have seen some devices re-join the ZHA network - but I don’t think the hue bulbs did that - i.e. as long as they were clean disconnected they were happy to wait for Z2M to become available.
I only have one SLZB 06, so I don’t think I can have both ZHA and Z2M running at the same time. I had deleted all the devices under ZHA. I completely re-flashed the SLZB 06 from a USB connection. I thought that maybe the firmware was corrupt.
I did try one other zigbee device that has never been paired before. It does not see that either. Maybe my coordinator is bad? It did work under ZHA for awhile.
Guess I could buy another bulb and that works or not. Having spent a lot on bulbs, I’m hesitant to spend more
That is my understanding too - that one coordinator can only be used for one Zigbee network.
Frankly I was scared I would end up in the same position as you are now, so decided to purchase a second coordinator (my first was a Sonoff Dongle, the second was a ZBT-2).
I choose the ZBT-2 because I thought that it would work pretty much out of the box with either ZHA or Z2M - I did end up having to flash it to a newer version of the firmware, however other than that it did “just work”.
I wanted to only have one network (everything on Z2M) and I was able to do that for a while - however I now have a single device (a Sonoff Temp sensor) that works better on ZHA - so I have ended up using both coordinators anyway.
I am not sure how to define “bad” it could be hardware, firmware or something related to your settings.
Hue bulbs have a reputation for being “sticky” - being difficult to reset / move to other networks - which is why I suggested trying a different device - basically anything that has a “pairing/reset” button you can press to force it into pairing mode.
For now I would suggest trying to get back online / go back to ZHA.
Once you are back to a working configuration you can make a decision about what you want to try next.
I finally got this to work. I found a post that said disabling join for 20 seconds and re-enabling it fixes the problem. No idea why. I had one out of 5 bulbs that suddenly came back. Soon after I found the post and tried it. The other 4 came back right way.
